Answer 1

Answer #1

A relationship between between energy and a certain frequesncy of electromagnetic wave in frame of quantum machenics is E=H*f --------------(eqn.1)

where E= energy

H = plank constant

f= frequency given

so,

H=6.67* 10^(-34)

f=3.1MHZ = 3.1 * 1000000 /sec

so putting values in eqn.1

E= ( 6.67 * 10^-34) * (3.1*1000000) JOULE

E= 2.0* 10^-27

SO D Part is answer

To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol λ (lowercase Greek "lambda"), is usually measured in meters. Every wave also has a frequency, which is the number of wavelengths that pass a certain point during a given period of time. Frequency, given the symbol...
